First file of, what...1000's?

config.h, c.h *and* elog.h...added elog.h

2. Reap unused tuples too
3. Reap empty pages
4. Check if a page is initialized, initialize it if not
   and reap it
5. Binary search in list of reapped pages/tids to check
   is the heap' tid pointed by a index' tuple on this list
   (it's mu-u-uch faster)

Get rid of ESCAPE_PATCH ifdef, as its on by default, and there is no
apparent reason for turning it off...it fixes a bug

Removed #ifdef's for OPENLINK_PATCH.  We enable it by default, and nobody
*has* to enable the functionality, but no reason to retain the "old code"

features(?) are available

Document any '#ifdef' segments found in config.h

Remove gistold.c, since it was older copy of gist.c

centralized configurations/porting...

config.h file

Further ports should *really* avoid backend/port and make use of
config.h

	- created a HAVE_TZSET define for this purpose

Thanks D'Arcy.

distinguish between char and char(1).

I hope everyone has sys/socket.h.

If I have introduced any syntax errors with this, I will patch them in
the morning, and Marc will have a good laugh.

cache.  I found if I manually added a line to flush the whole relation
cache, the assert error disappeared.  Looking through the code, I found
that the relation cache is flushed at the end of each query if the
reference count is zero for the relation.  However, printf's showed that
the rd_relcnt(reference count) for the accessed query was not returning
to zero after each query.

It turns out the parser was doing a heap_ropen in parser/analyze.c to
get information about the table's columns, but was not doing a
heap_close.

This was causing the query after the ALTER TABLE ADD to see the old
table structure, and the executor's assert was reporting the problem.
